Greenhouse Heating and Monitoring System Students: Riccardo Amador, Mallory Bartolovich, Jamal Odeh, Zhenlu Song, Jeffrey Rhine, and Greg Vaughn Instructor: Dr. Zhiqiang Gao Project Sponsor: Virtec Enterprises; Primary Contact: Tim Smith Department of Electrical Engineering, Washkewicz College of Engineering Cleveland State University Hydronic System Objectives Design Components • Once the seeds have germinated and have enough root structure, they will be arranged in gutter where the roots dangle freely • A continuous pump circulates water and nutrients, heated by heat exchanger • The liquid nutrients run down the gutter, flowing past the roots, then flowing back into pipes • Generate sustainable heat source • Monitor temperature and humidity • Maintain water temperature between 70°F to 80˚F in hydroponic system • Reduce manual labor • • • • Wireless Sensor Network Photovoltaic Power System Jean Pain Compost Heater Temperature Based Pump Control Site Map: Photovoltaic Power System • 50W/17.8V Solar Panel • 12V Photovoltaic Battery • 22V 7 Amp charge controller to regulate charge on battery from solar panel • Inverter to go from 12V DC to 120V AC and power the pump system Solar Panel Charge Controller 12V DC Solar Battery Inverter 120V AC Load Vertical Farming Temperature Based Pump Control Sensor Nodes Google Maps Jean Pain Compost Heater Base Station Wireless Sensor Network • Wireless sensor network system operated by Arduino hardware • Solar powered sensor nodes collect temperature and humidity information • Enters low power state after data transition • Base station receives information from sensor nodes, and sends to LCD display and computer serial port in real-time • Computer reads data from serial port, adds time stamps, and labels it into a file • Made of layered decomposing mulch and food waste • Dimensions of 10’ wide, 20’ length, and 4.5’ high • Wire mesh and metal posts to hold in place • Perforated tubing for aeration to keep pile active and eliminate turning • Water flowing through coiled pipe to absorb heat • Heat exchanger transfers heat to hydroponic system • Thermocouple used for temperature regulation • Hydroponic water less than 70°F activates pump until water reaches 80°F • Flow rate varies between 1-4 gal/min • Pump is relay activated • Controller integrated into pump by manufacturer Future Work • Retractable cover for greenhouse • Expanded sensor network to entire facility • Large scale photovoltaic power system for entire facility • More compost piles to ensure high temperature output • Optimize compost mixture for high quality, predictable output
